출애굽기 34:29의 Chasidut

Exodus 2:10, “She named him Moses, for I have pulled ‎him from the water.” There is a rule that when we have a ‎combination of light, water and fire, the creature whose soul ‎‎(essence) consists of fire can elevate itself to the level of water, ‎whereas the creature whose essence is water can elevate itself to ‎the level of light. Seeing that Moses was essentially connected to ‎water, having been “pulled from the water,” he can elevate itself ‎to the level of light. This principle is alluded to in Exodus 34,29 ‎ולא ידע משה כי קרן עור פניו‎, “Moses was unaware that the skin of his ‎face radiated light.”‎
‎[This “rule,” I have found explained in an article on ‎‎Parshat Miketz where Pharaoh is described as standing above ‎the water, and the expressions ‎יאור, נהר,אור‎ are explained also by ‎Onkelos as basically parts of one basic concept. When on different ‎levels of spiritual significance, they are called by correspondingly ‎different names. The interested reader will find a very ‎enlightening article about this written in 2004 in Google under ‎the heading ‎פרשת מקץ‎. The question I had asked Google, was: ‎אור, ‏אש, ומים‎. Ed.]‎

This verse make these afflictions depend upon the skin. This is based on the verse that says: "...the Lord God fashioned garments of skin for the man and his wife and God dressed them." (Genesis 3:21) The Midrash refers to a distinction between the "garments of skin" and "garments of light." It was because of sin that they came to be garbed in this coarse clothing, the skin of the snake. All of corporeality derives from there. Previously, they were in a spiritual state, as is said of the future. At the giving of the Torah, too, Israel were ready for this state. That is why it says of Moses that the skin of his face shone. (Exodus 34:29) He so redeemed "skin" that he was lit up through the shining speculum. But we did not remain at that rung. Therefore, the afflictions reappeared; the Midrash teaches that it was sin that made us again impaired. It is also known, however, that the skin is porous, containing many tiny holes. These allow the light to shine through its "shells." Only sin clogs up those pores, so that "darkness covers the earth." (Isaiah 60:2) That is why "the leprous affliction" is translated [into Aramaic] as segiru or "closing." Now we also understand why the purification rites are assigned to Aaron and his sons the priests; it was they who set right the sin of the Golden Calf.
